All Aboard!

Three engineers and three accountants are traveling
by train to a conference. At the station, the three
accountants each buy a ticket and watch as the three
engineers only buy one ticket.

"How are three people going to travel on only one
ticket?" asks an accountant.

"Watch and you'll see," answered an engineer.

They all board the train. The accountants take their
respective seats but all three engineers cram into a
rest room and close the door behind them.

Shortly after the train has departed, the conductor
comes around collecting tickets. He knocks on the
restroom door and says, "Tickets, please!" The door
opens just a crack and a single arm emerges with a
ticket in hand. The conductor takes it and moves on.

The accountants see this and agree it is a clever idea.
So after the conference, the accountants decide to copy
the engineers on the return trip and save some money.

When they get to the station, they buy one ticket for the
return trip. To their astonishment, the engineers don't
buy a ticket at all.

"How are you going to travel without a ticket?" says one
perplexed accountant.

"Watch and you'll see," answered an engineer.

When they board the train all three accountants cram into
a restroom and the three engineers cram into another one
nearby. The train departs.

Shortly afterward, one of the engineers leaves his restroom
and walks over to the restroom where the accountants are
hiding. He knocks on the door and says, "Tickets, please!"
